Paper Abstract

Gain modulation ladar is a cutting-edge ladar system. To eliminate the image distortion caused by target movement, two ICCDs are adopted to detect simultaneously and get the range image of object. This article presents a research on the working mechanism and range resolution of non-scan ladar based on gain modulation. The research suggests that ICCD's relatively low SNR is one of the bottlenecks of further improvement of system performance. To address this issue, an improved system was designed and studied with regard to its range resolution. Experimental results indicated that the proposed system was superior to the ladar system adopting double ICCDs in the aspects of range resolution, etc.
